Fight fungi in the lawn with biological means
Mushrooms in the lawn are a major nuisance for every garden owner. This problem occurs particularly frequently with turf turf. This is mainly due to a high proportion of organic substances, which can vary depending on the manufacturer and the nature of the substrate. Fighting fungi in the lawn is difficult, but if you follow a few guidelines, you can get rid of them.
Cause of fungus on green spaces
- The mushrooms sprout mainly in humid and warm weather conditions. In the garden you can often find them where under the race Tree roots run away. These fungi, which grow above the tree roots, usually keep coming back over many years, they are very stubborn.
- Another form is ring-shaped fungal plexuses in the lawn. These are known as witch rings. The ring-shaped plexus is based on an underground mycelium (mushroom plexus) that will spread over time if you don't do anything about it.
How to prevent witch rings in the lawn
- Witch rings are ring-shaped braids of mushrooms made of hat mushrooms 2-5 cm high. Some types of fungus that form such witch rings have a highly water-repellent mycelium (fungal network) that causes the lawn to dry out. The problem is particularly evident on sandy, nutrient-poor soils. In addition, so-called lawn thatch promotes the growth of fungi. This thatch occurs when the grass has grown too high and too dense, or when residues from the lawn clippings have remained in the sward. These fungi are more likely to appear in the soil if there is a lack of potassium.
- The formation of such witch rings cannot be completely ruled out, but there are a number of preventive measures that can be taken to make the lawn more resistant to infestation. A balanced supply of nutrients and adequate ventilation of the soil are important. You should always remove thatch and freshly cut lawn immediately scarify (ventilate). Fertilizing the lawn once or twice a year with a slow release fertilizer is recommended. In addition, you should feed the lawn with a high-potassium-containing autumn lawn fertilizer in late summer.
- When sowing the lawn, it must be ensured that the Grasses germinate quickly and grow vigorously. If the soil is poorly ventilated, this promotes the growth of such fungal plexuses. Nitrogen fertilizer, which is applied very late, leads to a strong growth of the lawn before winter and thus promotes fungal infestation. Leaves on the lawn should be completely removed before winter.

Ways to combat these growths
- Simple fungi in the lawn, which can form directly after the lawn has been created through too intensive watering, are for the Lawns are harmless and usually disappear on their own as soon as the lawn has grown well and watering has been reduced is.
- Before each treatment, the existing fungi should always be carefully removed. If this is not done, the spores can spread and spread further. If the part of the lawn with the witch ring becomes discolored or even dies, you should only do this area with it compost fertilize and mow the lawn more often, the mushrooms usually disappear on their own. In this case you should not use mineral fertilizers and especially nitrogenous fertilizers.
- Another way to fight the fungus is to loosen up and water the soil thoroughly. It is best to prick deep into the witch's ring in spring or autumn with a dung fork or digging fork Tear the mycelium (mushroom network) with the fork by gently lifting the sward several times at different points Place. You should then water this area thoroughly and keep it very wet for at least a week.
- Another helpful but laborious method of removing witch rings is to replace the floor. After removing the mushrooms, the soil must be dug up to an area of 30 cm deep and 60 cm on each side of the mushroom network and replaced with healthy soil. Afterwards, new lawn can be sown or Turf be interpreted.
